Instrumentation, Op Amps, Buffer Amps FAQ

How does the input bias current cancellation affect circuit design?

The internal cancellation circuit makes the input bias currents uncorrelated. Therefore, unlike JFET amplifiers, external resistance balancing at the input pins is not recommended and may increase error.

What is the input common mode voltage range?

The input stage operates between VEE + 0.8V and VCC – 0.9V. Exceeding this range causes the gain to drop to zero but does not result in phase reversal.
